Or what :-) Yeah I am also more familiar with NTC. But those descriptions originally come from a spreadsheet we're given, and they do include NTF as an acronym. eg. search for NTF in here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/pmu-events/arch/powerpc/power9/metrics.json >From the context it does presumably mean "next to finish". cheers
